Interannual spectral consistency and spatial uncertainties in UAV‐based detection of boreal and subarctic mire plant communities

Remote Sensing in Ecology and Conservation, EarlyView.
UAVs provide high spatial resolution imagery to detect and assess the spatial complexity of peatland vegetation. We used interannual multispectral data from aapa and palsa mires in Finland to classify plant communities using Random Forest. Based on class membership probabilities, we generated maps showing the second most likely classes and an ...

Spatial distribution and drivers of aboveground forest biomass in Mexico using GEDI and national forest inventory data

Remote Sensing in Ecology and Conservation, EarlyView.
GEDI LiDAR‐derived biomass models were calibrated using local field data across various forest types in Mexico, resulting in a significant improvement in AGBD estimation accuracy compared to the standard GEDI products. The models reduced biomass estimation errors by over 30% and showed the highest accuracy in areas with moderate slopes and low forest ...

Investigating boreal forest successional stages in Alaska and Northwest Canada using UAV‐LiDAR and RGB and a community detection network

Remote Sensing in Ecology and Conservation, EarlyView.
This study develops a novel application of UAV‐LiDAR and Red Green Blue (RGB) data and network analysis to enhance our understanding of boreal forest succession. The results indicate that tree height and spectral variables are the most influential predictors of plant functional type in random forest algorithms, and high overall accuracies were attained.

Phylogeny and divergence times of the African and Malagasy Podocarpus (Podocarpaceae) and their taxonomic and biogeographic implications

TAXON, EarlyView.
Abstract Podocarpus is the most speciose genus of the podocarp family (Podocarpaceae) widely distributed in the mountain forests of subtropical and tropical Asia, the Neotropics and Australasia, where its members have been shown to have had multiple origins.

Dismantling the genus Tarenna (Rubiaceae: Pavetteae) in Africa and Madagascar, with the description of three new genera

TAXON, EarlyView.
Abstract As presently circumscribed, the Paleotropical genus Tarenna, belonging to the tribe Pavetteae (Rubiaceae), comprises about 200 species and has its centres of diversity in tropical Asia and Africa. Previous molecular phylogenetic studies of the tribe revealed the polyphyly of Tarenna, suggesting that the genus needs to be recircumscribed ...

The Entangled Object of Language Ideology: Socio‐Material Stories of Becoming Content Teachers

TESOL Quarterly, EarlyView.
Abstract As countries around the world experience a surge of individuals who come from culturally and linguistically diverse (CLD) backgrounds, teacher education programs are reimagining ways to train content teachers with the necessary linguistic awareness, pedagogical tools, and skills to support CLD students while also incorporating teachers ...

DURATION OF LEAVES IN EVERGREENS

American Journal of Botany, 1917
While the duration of leaves in evergreens is not at all a new subject, very little systematic work seems to have been done toward determining durations for an extended list of evergreen species. This work was begun for the purpose of determining the leaf duration of the evergreen species of trees and shrubs in western Washington.
